Good suggestions there Beat, I'll look into these Eq's.
Even before using the ORR recording as a reference I started with sweeping. It's a good way to find some frequencies that bother me. To shape the timbre, however, I find that I'm not trained enough to imagine the effects of broader, more subtle eq settings. So, sweeping with a narrow q helps me finding single frequencies I'd like to dial back or up, but to really shape the tone I have a feeling that at some places broad(er) q's are important. Maybe I should simply try to sweep with broader q-settings as well?
Despite the great help so far, if anybody is willing to share some DS specific settings I'd appreciate that much.
